Kingdom is a really weird series, because it started out as a popcorn-snack-sized tower defense game that then grew to become a proper old-school campaign game... But each step towards that final product is its *own separate game*
But Kingdom: Two Crowns is still weirdly... Unfinished? Once you unlock the ability to clear islands you just go down the list, and after the fifth island the credits roll. There's no mechanical difference between the "finale" of each island. No final boss, not even a "you beat the whole game!" message. It just unceremoniously ends.
Idk, it just feels weird to me that stuff like the victory plaque and the coat of arms are all directly taken from Kingdom: New Lands, to the point where it doesn't even make sense anymore— you get the big crown from beating the fourth island, and then the skulls from the fifth, but in New Lands you got the skulls from the skull island???—but after no updates for like a year the devs shot out the gate with "hey we made a crossover skin for the game!!"
Well, anyway, I love K2C. I also love the Dead Lands campaign, definitely my favorite so far. I'm just a little confused about what the devs are prioritizing— and hesitant at the thought of another polishing update being sold as yet another goddamn full price Kingdom game
So each game is this weird snapshot of game development. The first game has no endgame goal and relies on arcade mechanics, the second game has multiple areas that elaborate on that concept, and the third game ties them all together into a single cohesive campaign setting.
